Well, it comes a time in a Bob lover's life when they have to accept that some people just don't see how amazing he really is..
I would never consider any of Bob's work as "jibberish" or him as a heartless person..
(to that "heartless" bit, i'd like to direct you to these lyrics:

I do understand, that Bob would sometimes act rude or out of the ordinary, and he did lie about many things, yes. But I mean, you can't blame him for that. Aren't others rude and liars? Just because he was famous and his lies were revealed, doesn't mean that he's any worse than anyone else.
I personally find it quite easy to overlook these minor faults, though, and find a truly wonderful and beautiful person. His lyrics are deep and wonderful, and his so called "nasal tones" happen to be pretty much the best I've ever heard.
